Still not what I would consider to be mobile friendly, but it's a start.

Here's my final JS:

add_action( 'wp_head', function () { ?>
<script>
// For Forum info divs
jQuery(document).ready(function($) {
jQuery(".wpforo-forum-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Extended layout topic titles
jQuery(".wpf-forum-item").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Threaded layout topic titles
jQuery(".wpf-thread").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
	// For Topics
$(".wpforo-topic-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
});

</script>
<?php } );

And my final CSS (to show the hand on desktop): 

div.wpforo-forum-info:hover {
    cursor: hand;
    cursor: pointer;
    opacity: .9;
}

div.wpf-forum-item:hover {
    cursor: hand;
    cursor: pointer;
    opacity: .9;
}

div.wpf-thread:hover {
    cursor: hand;
    cursor: pointer;
    opacity: .9;
}

div.wpforo-topic-info:hover {
    cursor: hand;
    cursor: pointer;
    opacity: .9;
}

The code does work for the limited scenarios on my dev board. You have to use the div and selector IDs appropriate to what your board uses and substitute those in the snippet provided by me. Each layout; Extended,Q&A,Threaded,Simplified will use unique div structures.

Example:

// For Simplified layout forum divs
jQuery(document).ready(function($) {
jQuery("#wpforo #wpforo-wrap > div.wpforo-main.wpft-forum > div.wpforo-content > div.wpfl-2 >").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});

It might prove impossible to make topic divs clickable in certain layout formats.

Use your browser developer tools to find the appropriate div IDs

It didn't reject it this time, but it isn't working.

I tested this snippet now on a dev board, it works on mobile (Opera & Chrome) and desktop.

Full code:

add_action( 'wp_head', function () { ?>
<script>
// For Forum info divs
jQuery(document).ready(function($) {
jQuery(" > div > div.wpforo-forum-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Extended layout topic titles
jQuery(document).ready(function($) {
jQuery("#wpforo #wpforo-wrap > div.wpforo-main.wpft-topic > div.wpforo-content > div.wpfl-1 >").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Threaded layout topic titles
jQuery("#wpf-cat-18 > div.wpf-threads > div.wpf-thread-list > div").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
});
});

</script>
<?php } );

// For Forum info divs - if you have links in your forum description they will only be clickable from within the forum, not on the main index. 
jQuery(document).ready(function($) {
$(".wpforo-forum-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Extended layout topic titles
$(".wpf-forum-item").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Threaded layout topic titles
$(".wpf-thread").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Topics
$(".wpforo-topic-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
});

For the first section

jQuery(document).ready(function($) {
jQuery(" > div > div.wpforo-forum-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;

If I remove > div > div, then it works just as the other code did (it's pretty much the same). But leaving that in doesn't work at all and the column is not clickable.

As for the other two sections, I wouldn't begin to know where to even start on editing them to work.

So I added this code in the code snippets plugin and the first error I got was < on line 1. So I removed the script lines and now the error I get is:

The code snippet you are trying to save produced a fatal error on line 3:

syntax error, unexpected '$', expecting variable (T_VARIABLE)

clicking on the words

Not sure what you mean by "words" so here is a quick n dirty snippet to cover a few scenarios (not tested yet):

<script>
// For Forum info divs - if you have links in your forum description they will only be clickable from within the forum, not on the main index. 
jQuery(document).ready(function($) {
jQuery(" > div > div.wpforo-forum-info").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Extended layout topic titles
jQuery(document).ready(function($) {
jQuery("#wpforo #wpforo-wrap > div.wpforo-main.wpft-topic > div.wpforo-content > div.wpfl-1 >").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
// For Threaded layout topic titles
jQuery("#wpf-cat-18 > div.wpf-threads > div.wpf-thread-list > div").click(function(){
window.location = $(this).find("a:first").attr("href");
return false;
});
});
});

</script>

Which allows me to achieve what I want to do on desktop, but it doesn't work on mobile. It also requires me to add JS, which could be overwritten on plugin update.

Has anyone been able to do this?

I'd like my forum to be more mobile friendly and clicking on the words is harder because they're small. How can I make it so the entire column is clickable, not just the words?

Thanks!
